We have developed a new AMLCD with multiple ambient light sensors (ALSs) for reducing backlight (BL) power consumption, and false sensing of ambient illuminance. ALSs perform well in showing BL control for power-saving, even though one of the sensors is covered by a finger shadow. Photo-electrical characteristics with well linearity and reliability under long-term operation were observed.
